Electricity&electrical Safety Flashcards
Aka insulator/ a material that does not transmit electricity
Nonconductor
Abbreviated as AC/a rapid and interrupted current/ flowing first in one direction and then in the opposite direction/ produced by mechanical means and changes directions 60 times per second
Alternating current
Is an apparatus that changes alternating current to direct current
Rectifier
Abbreviated as A/AKA amp/ a unit that measures the strength of an electric current
Ampere
Abbreviated as mA/ is 1/1,000 of an ampere
Milliampere
The current used for facial and scalp treatments is measured in____/ an ampere current would be much too___
Milliamperes/strong
If used for facials and scalp treatments, an ___ current would damage the skin or body
Ampere
Abbreviated as O/ unit that is measures the resistance of an electric current
Ohm
Abbreviated as W/ is a unit that measures how much electric energy is being used in one second.
Watt
A 40-watt lightbulb uses 40 watts of energy per
Second
If excessive current passes through a circuit or a fuse, the ___\ turns off the circuit to prevent overheating
Circuit breaker
Is designed to protect from electrical shock by interrupting a household circuit when there is a leak in the circuit
Ground fault interrupter (GFI)
It is important that you take signs of wear and tear seriously and __ or __ using appliances or outlets as soon as you notice these signs
Replace/ discontinue
If you drop an electrical appliance in water…
If outlet is GFI protected, you can unplug from wall.
Do not have one hand in water and one at the outlet
Never use and appliance that has been
Dropped in water
Currents used in electrical facial and scalp treatments are called
Modalities
Aka a probe/ an applicator for directing electric current from an electro therapy device to the client’s skin
Electrode
Refers to the likes of an electric current, either positive or negative
Polarity
Positive electrode is called an
Anode
The anode is usually _ and marked with a P or a plus sign
Red
The main modalities used in beauty and wellness services are
Galvanic current, micro current, and Tesla high frequency current
Is the process of using water soluble products into the skin with the use of electric current, such as the use of the positive and negative poles of a galvanic machine
Iontophoresis
Is an extremely low level of electricity that mirrors the body’s natural electrical impulses
Microcurrent
Infrared red light, visible light, and ultraviolet light used for light therapy services
Light waves
Each type of energy has its own
Wavelength
The distance between successive peaks of electromagnetic waves
Wavelength
Is the part of the electromagnetic spectrum that can be seen
Visible light
The visible spectrum of light makes up only ___% of natural sunlight
35
Natural sunlight is made up of 3 types of light
Visible light-35%
Invisible infrared-60%
Unviable ultraviolet-5%
Is often called the burning light because it’s most associated with sunburns/excessive use of both uva and uvb can cause skin cancers
Ultraviolet B (uvb)
Blocked by the ozone layer/often is effective at killing bacteria viruses mold and other pathogens
Ultraviolet c (uvc)
Substances that speed up chemical reactions
Catalysts
Aka phototherapy/application of light rays to the skin for the treatment of wrinkles, capillaries, or pigmentation or for hair removal
Light therapy
